TYPO3 Unverified Password Change for Backend Users ### Problem The backend user management interface allows password changes without requiring the current password. When an administrator updates their own account or modifies other user accounts via the admin interface, the current password is not requested for verification. This behavior may lower the protection against unauthorized access in scenarios where an admin session is hijacked or left unattended, as it enables password changes without additional authentication. ### Solution Update to TYPO3 versions 9.5.51 ELTS, 10.4.50 ELTS, 11.5.44 ELTS, 12.4.31 LTS, 13.4.12 LTS that fix the problem described. > [!NOTE] > In these versions, administrators are required to verify their identity through step-up authentication (also known as sudo mode) when changing backend user passwords. ### Credits Thanks to the National Cyber Security Center (NCSC) of Switzerland for reporting this issue, and to TYPO3 core & security team member Benjamin Franzke for fixing it. |

TYPO3 vulnerable to an Uncontrolled Resource Consumption in the ShowImageController ### Problem The `ShowImageController` (_eID tx_cms_showpic_) lacks a cryptographic HMAC-signature on the `frame` HTTP query parameter (e.g. `/index.php?eID=tx_cms_showpic?file=3&...&frame=12345`). This allows adversaries to instruct the system to produce an arbitrary number of thumbnail images on the server side. ### Solution Update to TYPO3 versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, 13.1.1 that fix the problem described. #### ℹ️ **Strong security defaults - Manual actions required** The `frame` HTTP query parameter is now ignored, since it could not be used by core APIs. The new feature flag `security.frontend.allowInsecureFrameOptionInShowImageController` – which is disabled per default – can be used to reactivate the previous behavior. ### Credits Thanks to TYPO3 security team member Torben Hansen who reported this issue and to TYPO3 core & security team members Benjamin Mack and Benjamin Franzke who fixed the issue. ### References * [TYPO3-CORE-SA-2024-010](https://typo3.org/security/advisory/typo3-core-sa-2024-010) |

Unrestricted File Upload in Form Framework ### Problem Due to the lack of ensuring file extensions belong to configured allowed mime-types, attackers can upload arbitrary data with arbitrary file extensions - however, default _fileDenyPattern_ successfully blocked files like _.htaccess_ or _malicious.php_. TYPO3 Extbase extensions, which implement a file upload and do not implement a custom _TypeConverter_ to transform uploaded files into _FileReference_ domain model objects are affected by the vulnerability as well, since the _UploadedFileReferenceConverter_ of _ext:form_ handles the file upload and will accept files of any mime-type which are persisted to the default location. In any way, uploaded files are placed in the default location _/fileadmin/user_upload/_, in most scenarios keeping the submitted filename - which allows attackers to directly reference files, or even correctly guess filenames used by other individuals, disclosing this information. No authentication is required to exploit this vulnerability. ### Solution Update to TYPO3 versions 8.7.40, 9.5.25, 10.4.14, 11.1.1 that fix the problem described. Type converter _UploadedFileReferenceConverter_ is not registered globally anymore and just handles uploaded files within the scope of the Form Framework. Guessable storage location has changed from _/fileadmin/user_upload/form\_\<random-hash\>/_ to _/fileadmin/form_uploads/<random-40-bit>_. Allowed mime-types must match expected file extensions (e.g. _application/pdf_ must be _.pdf_, and cannot be _.html_). Extbase extensions, who rely on the global availability of the _UploadedFileReferenceConverter_ must now implement a custom _TypeConverter_ to handle file uploads or explicitly implement the ext:form _UploadedFileReferenceConverter_ with appropriate setting for accepted mime-types. ### Credits Thanks to Sebastian Michaelsen, Marc Lindemann, Oliver Eglseder, Markus Volkmer, Jakob Kunzmann, Johannes Regner, Richie Lee who reported this issue, and to TYPO3 core & security team members Oliver Hader & Benni Mack, as well as TYPO3 contributor Ralf Zimmermann who fixed the issue. ### References * [TYPO3-CORE-SA-2021-002](https://typo3.org/security/advisory/typo3-core-sa-2021-002) |

HTTP Host Header Injection ### Meta * CVSS: `CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N/E:F/RL:O/RC:C` (3.5) ### Problem It has been discovered that TYPO3 CMS is susceptible to host spoofing due to improper validation of the HTTP _Host_ header. TYPO3 uses the HTTP _Host_ header, for example, to generate absolute URLs during the frontend rendering process. Since the host header itself is provided by the client, it can be forged to any value, even in a name-based virtual hosts environment. This vulnerability is the same as described in [TYPO3-CORE-SA-2014-001 (CVE-2014-3941)](https://typo3.org/security/advisory/typo3-core-sa-2014-001/). A regression, introduced during TYPO3 v11 development, led to this situation. The already existing setting _$GLOBALS['TYPO3_CONF_VARS']['SYS']['trustedHostsPattern']_ (used as an effective mitigation strategy in previous TYPO3 versions) was not evaluated anymore, and reintroduced the vulnerability. ### Solution Update your instance to TYPO3 version 11.5.0 which addresses the problem described. ### Credits Thanks to TYPO3 framework merger Benjamin Franzke who reported and fixed the issue. ### References * [TYPO3-CORE-SA-2021-015](https://typo3.org/security/advisory/typo3-core-sa-2021-015) * [CVE-2014-3941](https://nvd.nist.gov/vuln/detail/CVE-2014-3941) reintroduced in TYPO3 v11.0.0 |

TYPO3 is vulnerable to Cross-Site Scripting via frontend rendering > ### CVSS: `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:H/A:L/E:F/RL:O/RC:C` (8.2) ### Problem TYPO3 core component `GeneralUtility::getIndpEnv()` uses the unfiltered server environment variable `PATH_INFO`, which allows attackers to inject malicious content. In combination with the TypoScript setting [`config.absRefPrefix=auto`](https://github.com/TYPO3/typo3/blob/v11.5.22/typo3/sysext/frontend/Classes/Controller/TypoScriptFrontendController.php#L2547-L2549), attackers can inject malicious HTML code into pages that have not yet been rendered and cached. As a result, injected values would be cached and delivered to other website visitors (persisted cross-site scripting). Individual code which relies on the resolved value of [`GeneralUtility::getIndpEnv('SCRIPT_NAME')`](https://github.com/TYPO3/typo3/blob/v11.5.22/typo3/sysext/core/Classes/Utility/GeneralUtility.php#L2481-L2484) and corresponding usages (as shown below) are vulnerable as well. - `GeneralUtility::getIndpEnv('PATH_INFO') ` - `GeneralUtility::getIndpEnv('SCRIPT_NAME') ` - `GeneralUtility::getIndpEnv('TYPO3_REQUEST_DIR')` - `GeneralUtility::getIndpEnv('TYPO3_REQUEST_SCRIPT')` - `GeneralUtility::getIndpEnv('TYPO3_SITE_PATH')` - `GeneralUtility::getIndpEnv('TYPO3_SITE_SCRIPT')` - `GeneralUtility::getIndpEnv('TYPO3_SITE_URL')` Installations of TYPO3 versions 8.7 and 9.x are probably only affected when server environment variable [`TYPO3_PATH_ROOT`](https://docs.typo3.org/m/typo3/reference-coreapi/9.5/en-us/ApiOverview/Environment/Index.html#configuring-environment-paths) is defined - which is the case if they were installed via Composer. Additional investigations confirmed that Apache and Microsoft IIS web servers using PHP-CGI (FPM, FCGI/FastCGI, or similar) are affected. There might be the risk that nginx is vulnerable as well. It was not possible to exploit Apache/mod_php scenarios. ### Solution The usage of server environment variable `PATH_INFO` has been removed from corresponding processings in `GeneralUtility::getIndpEnv()`. Besides that, the public property `TypoScriptFrontendController::$absRefPrefix` is encoded for both being used as a URI component and for being used as a prefix in an HTML context. This mitigates the cross-site scripting vulnerability. Update to TYPO3 versions 8.7.51 ELTS, 9.5.40 ELTS, 10.4.36 LTS, 11.5.23 LTS and 12.2.0 that fix the problem described above. > ℹ️ **Strong security defaults - Manual actions required** > Any web server using PHP-CGI (FPM, FCGI/FastCGI, or similar) needs to ensure that the PHP setting [**`cgi.fix_pathinfo=1`**](https://www.php.net/manual/en/ini.core.php#ini.cgi.fix-pathinfo) is used, which is the default PHP setting. In case this setting is not enabled, an exception is thrown to avoid continuing with invalid path information. For websites that cannot be patched timely the TypoScript setting [`config.absRefPrefix`](https://docs.typo3.org/m/typo3/reference-typoscript/main/en-us/Setup/Config/Index.html#absrefprefix) at least should be set to a static path value, instead of using `auto` - e.g. `config.absRefPrefix=/` - this **does not fix all aspects of the vulnerability**, and is just considered to be an intermediate mitigation to the most prominent manifestation. ### References * [TYPO3-CORE-SA-2023-001](https://typo3.org/security/advisory/typo3-core-sa-2023-001) * [TYPO3-CORE-PSA-2023-001](https://typo3.org/security/advisory/typo3-psa-2023-001) *pre-announcement* |

Cross-Site Scripting via Rich-Text Content > ### Meta > * CVSS: `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:F/RL:O/RC` (5.7) ### Problem Failing to properly parse, sanitize and encode malicious rich-text content, the content rendering process in the website frontend is vulnerable to cross-site scripting. Corresponding rendering instructions via TypoScript functionality _[HTMLparser](https://docs.typo3.org/m/typo3/reference-typoscript/10.4/en-us/Functions/Htmlparser.html)_ do not consider all potentially malicious HTML tag & attribute combinations per default. In addition, the lack of comprehensive default node configuration for rich-text fields in the backend user interface fosters this malfunction. In default scenarios, a valid backend user account is needed to exploit this vulnerability. In case custom plugins used in the website frontend accept and reflect rich-text content submitted by users, no authentication is required. ### Solution Update to TYPO3 versions 7.6.53 ELTS, 8.7.42 ELTS, 9.5.29, 10.4.19, 11.3.2 that fix the problem described above. Custom package _[typo3/html-sanitizer](https://github.com/TYPO3/html-sanitizer)_ - based on allow-lists only - takes care of sanitizing potentially malicious markup. The default behavior is based on safe and commonly used markup - however, this can be extended or restricted further in case it is necessary for individual scenarios. During the frontend rendering process, sanitization is applied to the default TypoScript path `lib.parseFunc`, which is implicitly used by the Fluid view-helper instruction `f:format.html`. Rich-text data persisted using the backend user interface is sanitized as well. Implementation details are explained in corresponding [ChangeLog documentation](https://docs.typo3.org/c/typo3/cms-core/master/en-us/Changelog/9.5.x/Important-94484-IntroduceHTMLSanitizer.html). ### Credits Thanks to Benjamin Stiber, Gert-Jan Jansma, Gábor Ács-Kurucz, Alexander Kellner, Richie Lee, Nina Rösch who reported this issue, and to TYPO3 security team member Oliver Hader, as well as TYPO3 contributor Susanne Moog who fixed the issue. ### References * [TYPO3-CORE-SA-2021-013](https://typo3.org/security/advisory/typo3-core-sa-2021-013) |

Broken Access Control in Form Framework ### Problem Due to improper input validation, attackers can by-pass restrictions of predefined options and submit arbitrary data in the Form Designer backend module of the Form Framework. In the default configuration of the Form Framework this allows attackers to explicitly allow arbitrary mime-types for file uploads - however, default _fileDenyPattern_ successfully blocked files like _.htaccess_ or _malicious.php_. Besides that, attackers can persist those files in any writable directory of the corresponding TYPO3 installation. A valid backend user account with access to the form module is needed to exploit this vulnerability. ### Solution Update to TYPO3 versions 8.7.40, 9.5.25, 10.4.14, 11.1.1 that fix the problem described. ### Credits Thanks to Richie Lee who reported this issue and to TYPO3 contributor Ralf Zimmermann who fixed the issue. ### References * [TYPO3-CORE-SA-2021-003](https://typo3.org/security/advisory/typo3-core-sa-2021-003) |

TYPO3 vulnerable to Improper Access Control Persisting File Abstraction Layer Entities via Data Handler ### Problem Entities of the File Abstraction Layer (FAL) could be persisted directly via `DataHandler`. This allowed attackers to reference files in the fallback storage directly and retrieve their file names and contents. The fallback storage ("zero-storage") is used as a backward compatibility layer for files located outside properly configured file storages and within the public web root directory. Exploiting this vulnerability requires a valid backend user account. ### Solution Update to TYPO3 versions 8.7.57 ELTS, 9.5.46 ELTS, 10.4.43 ELTS, 11.5.35 LTS, 12.4.11 LTS, 13.0.1 that fix the problem described. #### ℹ️ Strong security defaults - Manual actions required When persisting entities of the File Abstraction Layer directly via DataHandler, `sys_file` entities are now denied by default, and `sys_file_reference` & `sys_file_metadata` entities are not permitted to reference files in the fallback storage anymore. When importing data from secure origins, this must be explicitly enabled in the corresponding DataHandler instance by using `$dataHandler->isImporting = true;`. ### Credits Thanks to TYPO3 core & security team member Oliver Hader who reported and fixed the issue. ### References * [TYPO3-CORE-SA-2024-006](https://typo3.org/security/advisory/typo3-core-sa-2024-006) |

TYPO3 Allows Unrestricted File Upload in File Abstraction Layer ### Problem By design, the file management module in TYPO3’s backend user interface has historically allowed the upload of any file type, with the exception of those that are directly executable in a web server context. This lack of restriction means it is possible to upload files that may be considered potentially harmful, such as executable binaries (e.g., `.exe` files), or files with inconsistent file extensions and MIME types (for example, a file incorrectly named with a `.png` extension but actually carrying the MIME type `application/zip`). Although such files are not directly executable through the web server, their presence can introduce indirect risks. For example, third-party services such as antivirus scanners or malware detection systems might flag or block access to the website for end users if suspicious files are found. This could negatively affect the availability or reputation of the site. ### Solution Update to TYPO3 versions 9.5.51 ELTS, 10.4.50 ELTS, 11.5.44 ELTS, 12.4.31 LTS, 13.4.12 LTS that fix the problem described. > [!NOTE] > The mitigation strategies outlined below apply broadly to all file uploads handled through TYPO3's File Abstraction Layer (FAL), not just those performed via the backend interface. This means that any extension or custom integration leveraging FAL will also be subject to the new validation rules and configuration options. Developers are advised to review the implications for their code and refer to the [documentation of that change](https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog/12.4.x/Important-106240-EnforceFile-extensionsAndMime-typeConsistencyInFileAbstractionLayer.html) for guidance. > [!IMPORTANT] > > **Strong security defaults - Manual actions required** > > These versions introduce new configuration options to better control which files are permitted for upload and to improve consistency checks. > > A new configuration option, `$GLOBALS['TYPO3_CONF_VARS']['SYS']['miscfile_ext']`, has been added. This option allows administrators to explicitly define which file extensions should be permitted that are not already part of the built-in text or media file groups - examples include archive formats such as `zip` or `xz`. > > In addition, two new feature flags have been introduced to enhance security: > * `security.system.enforceAllowedFileExtensions`, enforces the defined list of allowed file extensions. This flag is enabled by default in new TYPO3 installations, but remains disabled in existing installations to prevent breaking changes. > * `security.system.enforceFileExtensionMimeTypeConsistency`, ensures that the uploaded file’s extension matches its actual MIME type, providing further validation of file integrity. This flag is active by default. > > It is recommended to configure the allowed file extensions via `$GLOBALS['TYPO3_CONF_VARS']['SYS']['miscfile_ext']` and to enable the feature flag `security.system.enforceAllowedFileExtensions` to enforce the restriction. ### Credits Thanks to Hamed Kohi for reporting this issue, and to TYPO3 core & security team member Oliver Hader for fixing it. |
